Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

open access: yesNordic Journal of Botany, EarlyView.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

The promise of digital herbarium specimens in large‐scale phenology research

open access: yesNew Phytologist, EarlyView.
Summary The online mobilization of herbaria has made tens of millions of specimens digitally available, revolutionizing investigations of phenology and plant responses to climate change. We identify two main themes associated with this growing body of research and highlight a selection of recent publications exemplifying: investigating phenology at ...

Bridging data silos to holistically model plant macrophenology

open access: yesNew Phytologist, EarlyView.
Summary Phenological response to global climate change can impact ecosystem functions. There are various data sources from which spatiotemporal and taxonomic phenological data may be obtained: mobilized herbaria, community science initiatives, observatory networks, and remote sensing.

Using reflectance spectra and Pl@ntNet to identify herbarium specimens: a case study with Lithocarpus

open access: yesNew Phytologist, EarlyView.
Summary The digitisation of plant collections is bringing large quantities of information into accessible electronic databases. However, in recent decades, traditional taxonomic work in collections has declined, meaning that more specimens are only determined to family or genus, particularly when lacking key identification structures.

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

open access: yesNew Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

open access: yesNew Phytologist, EarlyView.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

Documenting biodiversity with digital data: comparing and contrasting the efficacy of specimen‐based and observation‐based approaches

open access: yesNew Phytologist, EarlyView.
Summary Digitized herbarium specimens and iNaturalist observations provide invaluable plant biodiversity data. Combining these two data sources could create a more holistic representation of local biodiversity; however, understanding biases inherent to each is critical to determine how to best combine and utilize these data.

Using herbarium collections to study genetic responses to global change

open access: yesNew Phytologist, EarlyView.
Summary Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have made the extraction of genetic data from these preserved specimens increasingly feasible, enabling new insights into plant biodiversity and ...
